Which set of ordered pairs does not represent a function? Answer \( \begin{array}{l}\{(5,-3),(1,-1),(-1,8),(9,-1)\} \\ \\ \{(-1,-3),(2,-5),(-2,0),(6,-3)\} \\ \\ \{\{(-7,-3),(-6,4),(-2,-5),(0,-3)\} \\ \\ \{(7,1),(7,-7),(-8,3),(9,5)\}\end{array} \)

\( \frac{\sqrt{164+\sqrt{25}}}{\sqrt{140+\sqrt{16}}} \) işleminin sonucu kaçtır? \( \begin{array}{llll}\text { (A) } \frac{14}{13} & \text { B) } \frac{13}{12} & \text { C) } \frac{7}{6} & \text { D) } \frac{17}{12}\end{array} \)

7) Use the Laws of Logarithms to combine the expression: \( 4 \log x-\frac{1}{3} \log \left(x^{2}+1\right)+2 \log (x-1) \)

The logarithmic function \( \boldsymbol{y}=\log _{3}(\boldsymbol{x}-2) \) has a vertical asymptote at \( \boldsymbol{x}=\square \), an x-intercept at \( (\square, 0) \), and domain \( \square \)

Use technology to find points and then graph the function \( y=\sqrt{x}+5 \) following the instructions below. Plot at least four points with integer coordinates that fit on the axes below. Click a point to delete it.

Convert the complex number, \( z=2 \) cis \( \left(\frac{3 \pi}{2}\right) \), from polar to rectangular form. Enter your answer as \( a+b i \).
